In Part 1, we began to discuss the importance of oxygen sensor voltage codes. Voltage codes can be caused by sensors that are bad and stuck lean or rich. These codes can also be caused by lean or rich running conditions. The case studies we will focus on will look at pre-cat oxygen sensor codes, both caused by parts other than the O2 sensors.

Engine mechanical issues are becoming more common in our repair bays today, and they can be difficult to diagnose. Engines are built with more valves, camshafts and complex variable valve timing systems. All of these components fail, and there are very easy tests...
